  3. CVE-2026-20117
A vulnerability in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability exists because the web-based management interface of an affected system does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

Summary
  • (es) Una vulnerabilidad en la interfaz de gestión basada en web de Cisco Unified Contact Center Express (Unified CCX) podría permitir a un atacante remoto no autenticado realizar ataques de cross-site scripting (XSS) contra un usuario de la interfaz. Esta vulnerabilidad existe porque la interfaz de gestión basada en web de un sistema afectado no valida suficientemente la entrada proporcionada por el usuario. Un atacante podría explotar esta vulnerabilidad inyectando código malicioso en páginas específicas de la interfaz. Un exploit exitoso podría permitir al atacante ejecutar código de script arbitrario en el contexto de la interfaz afectada o acceder a información sensible basada en el navegador.
